trees

Some scientists wanted to count each and every one of the trees in China. Surprisingly, they have achieved it

China is an immense country, the fourth country with greater extension in the world after Russia, Canada and the United States. The country has a wide variety of ecosystems, some of which house a countless amount of trees. Or almost countless. 142.6 million trees. A new study has estimated the total number of trees in China. The result of the count is 142.6 billion. This implies that the Asian giant has about 100 trees per inhabitant. More than a count. The study not only offers a mere count of the number of trees but also offers us valuable information about its location, density and characteristics of the different types of ecosystems that can be found in China. For example, the team found that the coniferous forests of the temperate areas were the densest in the country, reaching some 720 trees per hectare. The 87.9 billion trees that can be found in this type of environments represent about 60% of the country’s total. A country of contrasts. The forested areas of China are especially concentrated in the south and northeast of the country. The study also analyzed the tree density of the different Chinese hydrographic basins, as well as the different administrative divisions of the Asian country. In view of drone. For the study, the team He turned to Lidar technologyan analogue of the radar that replaces radio waves with light waves. These sensors were mounted in drones to cover 1,400 square kilometers of wooded territory. The result: 400TB of processed data. The methodology used is not exempt from limitations. In dense forest areas, the tree canopy, the upper part of these trees, can overshadow the lidar view, causing smaller trees to be hidden from counting. That is why those responsible for the study believe that this is a conservative estimate of the number of trees in the country’s forests. The details of the study were published In an article In the magazine Science Bulletin. Protection plans The project will serve to evaluate Chinese environmental conservation plans.

In their search to make the increasingly productive olive trees, these researchers have had an idea: to throw coal

The jungle floor is between reddish or yellowish; He is sterile and ungrateful, blinding and distemper. It is plagued with mineral oxides or empty of calcareous materials. It is and has always been a bad ground. Therefore, when in the middle of the Amazon, the settlers met the ‘Terra Petra‘They couldn’t believe it. It was a black, tremendously fertile land, incredibly resistant to the decomposition of organic matter. For decades, nobody knew where he had been able to leave. A dark enigma for a bright future. Some said that the Andes volcanoes could have come, others suggested that they should be a product of sedimentation of the tertiary lakes. But, When analyzing they realized that they were truffled with ceramic remains, fish swords, jewelry and human objects. The miracle of the ‘Terra Preta’ was the miracle of huge agricultural communities mixing land, vegetable coal, organic material of all kinds and favoring the growth of an own ecosystem within them. Charcoal? Indeed. That same face The researchers stayed. The jungle peoples often use a burning system to create fertile soils. The problem is that they lose fertility quickly. With the ‘Terra Preta’ it does not happen and the secret is in that coal. What in jargon is known as ‘biochar’. And that is really working? That is what The European Soil O-Live project has been askedif the olive trees could treat with a mixture of biochar and compost. The result is what brings us here: what Yes it works. According to researchers at the University of Jaén, coal treatment increases oil production between 7 and 24%. That is, between 0.4 and 1.7 kilos of oil per olive tree. It is true that it is a preliminary investigation, but without a very promising place. And what do we want it for? That is, without this type of “treatments” Spain is already the place of the world where more oil occurs and not for: grows 15% per year. The problem is that the machine cannot stop because demand It grows even more. Where will this race take us, that voracity? That is one of the great questions of the century.
